Description
We discuss methods and preliminary results in a search for variable
stars in the Carina dSph galaxy. This galaxy presents a complex star
formation history and hosts a unique sample of variable stars. We
collected B,V time series data during different runs, from 1999 to 2004,
with the MOSAICII camera available at 4m CTIO telescope. The methodology
is based on correlations between a version of the Welch-Stetson
variability index, the variability probability of the Lomb-Scargle
periodogram, and general statistical parameters associated with the
individual light curves.
